Deadline has named one of the first new additions to the Sicario sequel Soldado.

Catherine Keener has joined the sequel that includes a returning Benicio Del Toro and Josh Brolin. She’ll be playing their CIA boss and the trade also confirms the terrorism connection to the cartels.

Keener will play Brolin’s boss, trying to navigate the gray area that Gillick and Graver live in as the tale turns to what else is being smuggled across the border between Mexico and the U.S. in the tunnels used to move drugs and illegal immigrants. Those tunnels also can be used to bring terrorists into the U.S.
